Value-packed wireless headphones

If you're looking for a solid set of Bluetooth headphones from a reputable brand, here's a smart choice. The Sennheiser HD 4.40BT headphones play music wirelessly from your phone and boast up to 25 hours of battery life. They're also comfortable and affordable, and they deliver strong Sennheiser sound with deep bass.

We've carried Sennheiser for so long, I often assume they're a household name. But if you don't know this celebrated headphone maker, they've been at it for over 70 years. So even grabbing a so-called "entry-level" pair of their wireless headphones should promise you good performance.  

My hands-on experience

"I got a chance to try these Sennheiser HD 4.40BT headphones... Light and comfortable. They play quite loud for Bluetooth headphones, so they work well on the go. I thought the powerful bass gave them a lot of energy, and I consider them a strong buy at this price.”

 — Jeff Miller, Crutchfield headphone guy

Comfort and convenience

Personally, I appreciate the modest design of the Sennheiser HD 4.40BT — not too plain, but not too showy, either. I think it's more important that headphones feel good, since you could be wearing them for long periods of time. Their oversized ear cups and well-padded headband help ensure they fit nicely.

And thanks to that built-in Bluetooth, you can keep your phone nearby or in your pocket while you move around freely. You can control your tunes or take phone calls using the tactile buttons on the right earcup.

Features

Overview: The Sennheiser HD 4.40BT over-ear wireless headphones are ideal for every day listening while you're on the go. With built-in Bluetooth, you can pair the headphones to your smart phone or tablet for wireless listening for hours. The headphones come with a USB charging cable, a straight audio cable, and a soft storage pouch.

Bluetooth: The HD 4.40BT headphones are compliant with the Bluetooth 4.0 standard, and are compatible with Bluetooth 1.1 through 4.0 devices with the following profiles: HFP (Hands-Free Profile), HSP (Headset Profile), AVRCP (Audio Video Remote Control Profile), and A2DP (Advanced Audio Distribution Profile). In addition, aptX audio coding provides high quality audio that is comparable to a wired connection. You can pair the headphones with most Apple and Android Bluetooth devices, including those with NFC (Near Field Communication).

Battery: The Bluetooth function is powered by a 3.7-volt 600mAh Lithium-Polymer rechargeable battery. The battery charges in approximately 2 hours using the supplied Micro USB charging cable. A full charge supplies enough power for 25 hours of wireless listening. The remaining battery level can be monitored through the flashing LED and voice prompts. The battery life may also be displayed on the screen of your smartphone or device.

On-board Controls: The HD 4.40BTs have built-in controls on the right ear cup for power, volume, and music/phone call control. Music controls include play/pause, skip to next track, skip to previous track, fast forward, and fast reverse. Phone controls include accept/end a call, reject call, call on hold, and toggle between 2 calls. Established calls can be transferred from the headphones to the smartphone by turning off the Bluetooth connection. Using the Voice Control function of your phone, you can make a call by speaking a command.

Audio Cable: The included 58" audio cable lets you listen to your music when the battery is exhausted, or when you cannot, or choose not to, use Bluetooth. The cable terminates into a slender right-angled 3.5mm plug that is compatible with most smartphone cases. The cable does not have an in-line remote, and the on-board controls do not work when the power is off.

Specifications:

  • Frequency Response: 18 Hz to 22 kHz
  • Impedance: 18 Ω
  • Sound Pressure Level (SPL): 113 dB (1 kHz, 1 Vrms)
  • Total Harmonic Distortion (THD): <0.5 % (1 kHz, 100 dB SPL)
  • Dimensions (Ear Cup): Width 2.99", Height 3.565", Depth 1.878"

Q
Can be use with a PS4 gaming console?
[ Ricky  Dec 19, 2018 ]

A
I don't think so. It has no microphone or wire input. It is just a wireless, sound cancelling headset for listening.
[ david  Dec 19, 2018 ]
A
Sorry, I am not sure since I bought this for a friend overseas and not sure what he was using it for besides listening to music.
[ DARSHANI  Dec 19, 2018 ]
A
I am not sure as I only use my headphones for music and occasionally Bluetooth on my laptop. If your PS4 is Bluetooth compatible, I don't see why these headphones wouldn't work with the PS4.
[ Scott  Dec 19, 2018 ]
Q
Just got these and they are beeping between songs. How do I stop this?
[ Summer  Nov 28, 2018 ]

A
I use my headphones for TV viewing more than music, but the only time I've experience random beeping, during play, was when the battery was getting low and charging was needed. A blue LED lite means fully charged.

A
blue tooth pairing very easy
[ ROSALINDA  Jul 18, 2017 ]
A
There is no physical connection necessary with these headphones. They are designed to work with Bluetooth compatable devices; like TV's, cell phones, book readers, music players, ect. I purchased my headphones to use with my Samsung UHD TV. I can stream movies and use the headphone to listen to them without worrying about the sound disturbing otherst. Decide what device you want/need to use the headphones with, then make sure that that device is Bluetooth compatible.
[ Ronald  Jul 17, 2017 ]
A
Hold down the power button until the light keeps flashing blue (about 5 seconds)
